Symfony + Docker, from development environment to production
summary
Demonstrates a CI/CD pipeline that builds compact, production-ready Docker images for Symfony apps and deploys them to a Kubernetes cluster. Covers concrete techniques: reuse docker-compose during builds, cache-friendly Dockerfile ordering and strict package pinning, caching then removing Composer artifacts, one-process-per-container design, and performing builds inside a Docker-in-Docker daemon with a private registry and automated Kubernetes rollout checks.
